Anisocoria | A condition in which the pupils are unequal in size. |
Astigmatism | A condition in which the eye does not focus properly because of uneven curvatures of the cornea. |
Audiometry | The use of an audiometer to measure hearing acuity. |

Dacryoadenitis | An inflammation of the lacrimal gland caused by a bacterial, viral, or fungal infection. |
Diplopia | The perception of two images of a single object; also known as double vision. |
Ectropion | The eversion of the edge of an eyelid. |
Emmetropia | The normal relationship between the refractive power of the eye and the shape of the eye that enables light rays to focus correctly on the retina. |
Entropion | The inversion of the edge of an eyelid. |
Esotropia | Strabismus characterized by an inward deviation of one or both eyes; also known as cross-eyes. |

Glaucoma | A group of diseases characterized by increased intraocular pressure that causes damage to the retinal nerve fibers and the optic nerve. |
Hemianopia | Blindness in one-half of the visual field. |
Hordeolum | A pus-filled and often painful lesion on the eyelid resulting from an acute infection in a sebaceous gland; also known as a stye. |
Hyperopia | A defect in which light rays focus beyond the retina; also known as farsightedness. |

Mydriasis | The dilation of the pupil. |
Myopia | A defect in which light rays focus in front of the retina; also known as nearsightedness. |
Myringotomy | A small surgical incision in the eardrum to relieve pressure from excess pus or fluid, or to create an opening for the placement of tympanostomy tubes. |
Nyctalopia | A condition in which an individual with normal daytime vision has difficulty seeing at night; also known as night blindness. |

Otorrhea | Any discharge from the ear. |
Otosclerosis | The ankylosis of the bones of the middle ear, resulting in a conductive hearing loss. |
Papilledema | The swelling of the optic nerve at the point of entrance into the eye through the optic disk. |
periorbital edema | Swelling of the tissues surrounding the eye or eyes. |
Photophobia | Excessive sensitivity to light, and can be the result of migraines, excessive wearing of contact lenses, drug use or inflammation. |
Presbycusis | A gradual loss of sensorineural hearing that occurs as the body ages. |
Presbyopia | The condition of common changes in the eyes that occur with aging. |

Scleritis | An inflammation of the sclera. |
sensorineural hearing loss | Develops when the auditory nerve or hair cells in the inner ear are damaged. |
Stapedectomy | The surgical removal of the top portion of the stapes bone and the insertion of a small prosthetic device known as a piston that conducts sound vibrations to the inner ear. |
Strabismus | A disorder in which the eyes point in different directions or are not aligned correctly because the eye muscles are unable to focus together. |
Tarsorrhaphy | The partial, or complete, suturing together of the upper and lower eyelids to protect the eye when the lids are paralyzed and unable to close normally. |
Tinnitus | A condition of ringing, buzzing, or roaring sound in one or both ears. |
